DiaPat® DN-PROteom test: Diabetes patients, take care of your kidneys!

The DiaPat® DN-PROteom test is the extremely reliable, non-invasive method for type I and type II diabetics to diagnose diabetic nephropathy (DN). DN as a complication of diabetes is gaining momentum. Previous preventive measures of the statutory health insurance could neither contain the dynamic nor achieve any other measurable success. The New England Journal of Medicine reported in a 20-year long-term study of irrelevant containment of the secondary disease of DN:

Gregg,E.W., Li,Y., Wang,J., Burrows,N.R., Ali,M.K., Rolka,D., Williams,D.E., and Geiss,L. (2014). Changes in diabetes-related complications in the United States, 1990-2010. N. Engl. J Med 370, 1514-1523.

The DiaPat® DN-PROteom test detects kidney disease years before current standards and the appearance of the first clinical symptoms due to irreparable kidney damage.

Your kidney insurance for a healthier, longer life.

Used at an early stage, the test for diabetics is a kind of insurance for the preservation of their kidneys and a longer, healthy life without dialysis. The DiaPat® DN-PROteom test can also be used to demonstrate the monitoring of an immediately applied individual drug therapy for already diseased kidneys.

 

 

DiaPat® DN-PROteom test: How does this work? What can the test do?

The DiaPat® DN-PROteom test analyzes 273 disease-specific proteins in the urine. He compares the result with a pattern of disease-specific proteins, biomarkers for diabetic nephropathy. In this way, the test detects chronic kidney disease 3-5 years before the first clinical symptom, and it does so with the utmost reliability (sensitivity [gr]85%, specificity [gr]85%)), earlier and more precisely than standard methods previously used: determination the albumin excretion or the GFR.

The early detection of diabetic nephropathy, which is possible with the DiaPat® DN-PROteom test, usually prevents fatal kidney failure or kidney replacement therapy (dialysis or kidney transplantation). Because an immediately applied drug therapy still has the chance to significantly improve the prognosis at this early stage of the disease. This means slowing down the progression of the disease or even preventing serious damage to the kidneys entirely.

 

 

Diabetic Nephropathy: What should I know?

Diabetic nephropathy is a frequently occurring kidney disease, a kidney disease as a result of long-term, not optimally controlled diabetes (diabetes mellitus type I, type II). An average of 10 to 15 years after the onset of their diabetes, 25% to 40% of diabetics suffer from this insidious kidney dysfunction. In Germany, diabetic nephropathy is the most common cause of kidney failure requiring dialysis.

Background: Diabetes mellitus is a chronic metabolic disease that causes high blood sugar. Reasons for this can be a lack of insulin (type I) or a lack of sensitivity of the body cells to insulin (type II). As a result, the body cannot fully absorb sugary foods (bread, pasta, rice, desserts). The contained sugar accumulates in the blood. This leads to an increased concentration of blood sugar and harmful deposits in the body's blood vessel system, including the kidney corpuscles, which serve as filters there.

Just as in general, the blood pressure in the kidney corpuscles also rises due to calcification of the renal arteries. The kidney's natural filtering function gradually fails. The doctor speaks of this kidney disease as diabetic nephropathy. If left untreated, it leads to approx. 2.5 years to chronic kidney failure. The diagnostic challenge here: the onset of nephropathy does not cause pain and is symptom-free, unnoticed.

Other risk factors for diabetic nephropathy: high blood pressure, age, family history, smoking, obesity.

 

Early detection step by step: our expert advice

Diabetic nephropathy is usually detected in clinical practice on the basis of albuminuria and/or an altered glomerular filtration rate (GFR). However, these common methods often do not respond until the filtration capacity of the renal corpuscles is already impaired. At this point, the kidney is already irreparably damaged.

Professor Dr. Dr. Diethelm Tschöpe, Heart and Diabetes Center NRW:
"For the first time, diabetic nephropathy can be diagnosed at an early stage with the DiaPat® DN-PROteom test and treated accordingly. For the patient, this reliable diagnostic method means a decisive advance in treatment time."

Professor Dr. Peter Rossing, Steno Diabetes Center, Gentofte/Kopenhagen:
"The early use of drug therapy increases the efficiency of the kidneys and prevents kidney replacement therapy. The effects of the therapy can be optimally checked with the DiaPat® DN-PROteom test."

In the meantime, it has also been proven that an earlier, intensive treatment can achieve significant therapeutic success if an earlier, reliable diagnosis can be made. Studies have shown that with the earlier detection of the DN and the more intensive treatment associated with it, the further progression of the DN can be stopped significantly, at least for a relevant period of time. With traditional diagnostics - especially the measurement of a single protein (the albumin protein content in urine) - the DN is recognized late. Often so late that pathological functional disorders or organ damage are irreversibly far advanced. The DiaPat® DN-PROteom test with 273 proteins / protein fragments, on the other hand, can detect diabetic nephropathy in its very early stages - up to 2 years earlier and more precisely than microalbuminuria.

DiaPat® DN-PROteom test: The path to the statutory health insurance system is paved.

By application of the National Association of Statutory Health Insurance Physicians (KBV) from 07/07/2011, the evaluation of the "proteome analysis in urine for the detection of diabetic nephropathy in patients with diabetes mellitus and arterial hypertension" according to § 135 paragraph 1 SGB V was applied for. After submitting the application on December 20, 2012, the Federal Joint Committee (G-BA) decided to commission the Institute for Quality and Efficiency in Health Care (IQWiG) with the assessment. The G-BA published the advisory topic on December 29, 2012 in the Federal Gazette in order to give experts and experts the opportunity to comment.
